In the drawings wherein like reference corresponding throughout the several views Figure 1 is a longitudinal sectional view of a refrigerant container in accordance with this invention showingthe adaptation thereof with respect to certain of the elements of a frozen product machine.

Figure 2 is a side elevation of a refrigerant container in accordance with this invenparts Figure 3 is a section on the line 3-3 Fig- The container includes a longitudinally disposed inner metallic cylinder 1 which slightly tapers from its rear to its front end, a longitudinally disposed outer metallic cylinder 2 of greater diameter and length than cylinder 1 and which slightly tapers from its rear to its front end, a sectional metallic front head member 3, a metallic rear head member 41, a permanently bright, metallic front cap 5 possessing a non-sweating characteristic, a metallic retaining disc or cap 6 for the rear end of the container, and a permanently bright metallic tapered sleeve 7 completely encompassing the outer metallic cylinder 2 and possessing a non-sweating characteristic. The thickness of the body of the sleeve 7 is less than the thickness of either one of the cylinders. The head members 3 and 4 in connection with the inner cylinder 1 provides a refrigerant chamber 8. Preferably the refrigerant will be in the form of brine.

The head member 8 is formed of two sections, one of which is indicated at 9 and the other at 10. The section 9 is in the form of a flat annulus having projecting rearwardly from its rear face an annular flange 12 positioned between the edges of the annulus. The section 10 is in the form of a circular disc 13 having an axial opening 14 and a forwardly directedannular flange 15 registering with the wall of the opening 14. The disc 10 abuts against the front'face of the annulus, secured by holdfast devices 16 to the annulus and extends across the opening provided by the annulus. .The' opening provided by the annulus is of materially greater diameter than the opening provided in the disc 13. The head member 3 is positioned within the outer cylinder 2 at a point rearwardly with respect to the front end of said cylinder 2. The head member 3 abuts against the front end of the inner cylinder 1 and the latter has its front end supported upon the flange 12.

The head member 4 is in the form of a circular disc 17 provided with an axial opening 18 and has formed integral with the front face, as well as projecting forwardly therefrom an annular flange 19. Tie head member 4 abuts against the inner face of the outer cylinder 2 and also against the rear end of the inner cylinder 1. The rear end of the inner cylinder 1 is supported upon the flange 19. The flanges 12 and 19 snugly engage the inner face of the cylinder 1 at the ends of the latter.

Positioned within the front end of the cylinder 2 and abutting against the forward face of the annulus 10, as well as snugly engaging the inner cylinder 2 is a metallic ring 20 of the desired thickness. The ring 20 has its front edge flush with the front edge of the outer cylinder 2.

Interposed between the cylinders 1 and 2 and abutting the head members 3, 4 is an insulating body 21 preferably in the form of cork and each side of said body has a coating of a preservative, preferably creosote. The coating at the outer side of body 21 is indicated at 22 and at the inner side at 23. The coatings of creosote extend from the head member 3 to the head member 4.

The front cap 5 includes a circular body portion 24 provided with an axial opening 25 and a forwardly directed angle shaped flange 26 which registers with the wall of the opening 25, that is to say the longitudinal leg of flange 26. The outer leg of flange 26 is extended inwardly from the longitudinal leg and opposes in spaced relation the flange 15. The body portion 24 is formed with forwardly directed angle shaped flange 27 having its longitudinal leg abutting the inner face of ring 20 and its other leg abutting against the front edge of ring 20 and the front edge of cylinder 2. The sleeve 7 has its front end seated upon the flange 27. Interposed between the body portion 24 of the front cap 5 and the front head member 3 is an insulating body 28 of cork having an axial opening 29. The insulating body 28 abuts against the inner face of the ring 20 throughout.

Spaced reinforcing bands 29 extend circumferentially of the sleeve 7 and which acts to couple the cylinders 1, 2, insulating body 21 and sleeve 7 together. The reinforcing bands are constructed of metal possessing a permanently bright and non-sweating characteristic. The outer cylinder 2 and sleeve 7 is extended at the bottom at its rear as at 30, 31 respectively. The extended portions 30, 31 act as a support for a refrigerant overflow collector 32, provided with an intake 33. The rear cap 6 is in the form of a circular disc and which ispositioned within the outer cylinder 2 forwardly with respect to the rear end of the latter and interposed between cap 6 and rear head member 4 is an insulating body 33 preferably in the form of cork. The rear cap 6 and insulating body 33 are apertured as at 34, 35 respectively for the passage of the journal 10.

The container includes a refrigerant overflow pipe 36 which leads to the overflow collector 32. The overflow pipe 36 communicates with the refrigerant chamber and extends through the rear head member 4, in sulating body 33 and rear cap 6. The insulating body 33 and rear cap are provided with axial openings 37, 38 respectively which register with the opening 18 formed in the rear head member 4. The container includes a drain pipe 39 which leads from the refrigerant chamber 8 and extends through the inner cylinder 1, insulating body 21, outer cylinder 2 and sleeve 7.

As illustrated the production elements of the machine are arranged in the refrigerant chamber 8 and are generally indicated at 40. The operating and supply means for the production elements 40 are generally indicated at 41 and extend through the aligning openings 18, 37 and 38. The discharge elements of the machine are generally indicated at 42 and they extend through the flanges 15 and 26. A packing means 43 is connected with the flange 15 and encompasses the elements 42.

The top of the container is provided with an intake opening 44 and communicating therewith is a hopper 45.

The sleeve 7 is formed of a ferrous alloy known as Alleghany metal. The alloy is composed principally of iron, chromium, nickel in the order named and containing small amounts of manganese, silicon and carbon.

The cylinders 1 and 2, as well as the head members are constructed of rust proof steel, the sleeve 7 and front and rear caps of a ferrous alloy.

A composite-insulated-refrigerant container as set up in a manner as herein before referred to will retain the freezing temperature, eliminates sweating, saves ice and provides for the external surface thereof to appear in a sanitary and bright condition.
